Capacitor and SMD Capacitor Codes Explained with Examples

In this Video, All types of capacitor codes – SMD Tantalum capacitor, SMD Aluminum Electrolytic capacitor, SMD Ceramic capacitor, EIA Standard SMD capacitor, Ceramic capacitor, Electrolytic capacitor codes Explained with Examples.

EIA Standard SMD capacitor code is marked with an alphabet letter that indicates significant digit value in picofarads, and the numerical number indicates its corresponding multiplier, By using the table shown in this video we can find out capacitance value.

SMD Ceramic capacitors are not marked, The color of the ceramic capacitor is helpful to identify its value,
Class-1 Ceramic capacitors are usually in white color, their values are below 1pf to some tens of picofarads,
Class-2 Ceramic capacitors are usually in light brown color, their values in the range between nanofarads to microfarads,
Class-3 Ceramic capacitors are usually in black or dark brown color, these are general purpose capacitors, Highly sensitive to temperature and high voltages.

SMD Aluminum Electrolytic capacitors are polarized, whose negative contact is marked on the case, The coding pattern is slightly different for different types of series, generally, their capacitance value is printed on their case and voltage rating is indicated with an alphabet letter.

SMD tantalum capacitors are polarized, their positive contact is marked on their surface, Two or three-digit coding scheme is used to represent their values just like resistor coding, the Voltage rating is labeled or indicated with an alphabet letter.

Ceramic capacitors are non-polarized and generally smaller in size, Two or three-digit code is printed on their surface just like resistor coding, Their capacitance value is in picofarads, To represent decimal point, the alphabet letter ‘R’ is used.
Their tolerance code is indicated with alphabet letters,
Their voltage rating is indicated with underline or alphabet letters.

Electrolytic capacitors are polarized, The stripe marking on its case indicates negative connection, Their capacitance values in microfarads and voltage ratings are directly printed on their case.

This video will be helpful to all students of science and engineering and working professionals in understanding capacitors coding schemes.
